Samsung EX2F - Raw shooting not possible - Please help

Just got the Samsung EX2F which does not allow me to shoot RAW. The option is there in the photo quality menu, but only Superfine (jpg), Fine (jpg) and Normal (jpg) is active (can be chosen), while RAW or RAW + Jpg combinations are inactive (cannot be chosen). No difference whether in Smart auto, P, S, A or Manual mode.

Please help! Is there an obvious reason or something to switch on or the camera is just faulty?
